Abstract

A method for nickel-titanium alloy dental reamers which are manufactured from a cylindrical metallic blank that is moved at a feed speed VA past a rotary grinding wheel whose disk, of variable diameter, determines a linear speed VL at which material is removed. The character is the following parameter: the feed speed VL is greater than 91440 cm/min, while the linear speed VA is less than 7.62 cm/min. The other objection of the invention is the said dental reamers.

Description

The manufacture method of dentist Ni-Ti alloy reamer
The present invention relates to the manufacture method of a kind of Ni-Ti alloy (being referred to as NITI) dentist reamer.
These dentist's reamers mainly are to make with a kind of metal cylinder blank, and they are made up of at least 40% titanium usually, although this ratio is not crucial for making in this way.
The metal blank rod the rotation emery wheel before with charging rate V AMove, the dish of the different-diameter of emery wheel has determined the linear speed V of revolving wheel cutting blank material L
The another one important parameter is by emery wheel particle size D GDecision, this is normally under the situation of corundum.
Described such method in US 5 464 362 patents, wherein claimed and described value is as follows:
-V ABe the 7.62-20.32 cm per minute,
-D GBeing higher than 200 draws.
Unexpectedly and with existing method in the situation of the complete contradiction of situation of some optimum conditions of existing show that opposite service condition provides identical at least result.
Therefore, the objective of the invention is to make dentist Ni-Ti alloy reamer, described dentist's reamer is made by a kind of cylindrical metal base, this base in the revolving wheel front with charging rate V AMove, the dish of the different-diameter of emery wheel has determined the cutting linear speed V of material L, it is characterized in that these parameters are as follows:
-V LBe higher than 91440 cm per minute,
-V ABe lower than 7.62 cm per minute.
Advantageously, the granularity of emery wheel particle is greater than 46 μ.
According to preferred embodiment a kind of, this emery wheel is that a kind of golden steel bores emery wheel.
Best, determined parameter is as follows:
-V L=2213 meters/minute
-V A=3.2 cm per minute.
Any other factors that of course it is to be understood that this method of enforcement all should be identical with existing method.

Claims (5)

1, the manufacture method of dentist Ni-Ti alloy reamer, described dentist's reamer is made by a kind of cylindrical metal base, this base in the revolving wheel front with charging rate V AMove, the dish of the different-diameter of emery wheel has determined the cutting linear speed V of material L, it is characterized in that these parameters are as follows:
-V LBe higher than 91440 cm per minute,
-V ABe lower than 7.62 cm per minute.
2, method according to claim 1 is characterized in that, the granularity of emery wheel particle is greater than 46 μ.
3, method according to claim 1 and 2 is characterized in that, this emery wheel is that a kind of golden steel bores emery wheel.
4, according to the described method of arbitrary claim among the claim 1-3, it is characterized in that its parameter is as follows:
-V L=2213 meters/minute
-V A=3.2 cm per minute.
5, according to the resulting dentist's reamer of the described method of arbitrary claim among the claim 1-4.
